Writing Ionic Compound Formulas ½ Sheet In-Class Practice – ANS KEY Complete the following table – you will need to write the charges of the ions first so you can do the cross over and down! Don’t forget to simplify! zinc iron (II) iron (III) gallium silver lead (IV) chloride ZnCl2 FeCl2 FeCl3 GaCl3 AgCl PbCl4 nitrate Zn(NO3)2 Fe(NO3)2 Fe(NO3)3 Ga(NO3)3 AgNO3 Pb(NO3)4 oxide ZnO FeO Fe2O3 Ga2O3 Ag2O PbO2 nitride Zn3N2 Fe3N2 FeN GaN Ag3N Pb3N4 sulfate ZnSO4 FeSO4 Fe2(SO4)3 Ga2(SO4)3 Ag2SO4 Pb(SO4)2 Complete the following practice problems – write the ions first, then write the completed (simplified if necessary) chemical formula. (see example for how to set it up!) 1) vanadium (III) selenide _ __V+3 Se-2 2) copper (II) chloride ____Cu+2 → V2Se3___ Cl-1_____→___CuCl2___ 3) lithium acetate __ Li+1 C2H3O2-1__→__LiC2H3O2____ 4) beryllium oxide __ Be+2 O-2__→____BeO____ 5) sodium sulfate ___ Na+1 SO4-2__→___Na2SO4______ 6) ammonium nitrate __ NH4+ NO3-1__→____NH4NO3____
